    Specific warnings and cautions are found throughout the Operation Manual where they apply, but may not appear in this summary. Before installing and operating the SBS Balance System, it is necessary to read and understand the entirety of this manual. After reading the Operation Manual, contact Accretech SBS, Inc.

  • Page 8: Balance Theory

    In both cases, the imbalance is given in terms of a mass multiplied by a distance, with (grams)(centimeters) being the units used for reference by the system. The SBS system with SB-1000 control can operate in either Automatic Balance mode, or Manual Balance mode in order to correct for wheel imbalance.

  • Page 9: Manual Balance Overview

    Manual Balance Overview The SB-1000 control can also be configured to be used as an aid in performing manual balance operations, where the cost of a fully automatic system is not warranted.

  • Page 10: System Installation

    POWER SUPPLY. Terminal block connection for power input. 22 VDC to 26 VDC, 3.5A max at 22 VDC. There is no power switch on the SB-1000, as it is designed for constant operation. If power must be disconnected by the user, a separate switch on the power line may be installed at installation.

  • Page 11: Vibration Sensor Location

    M5 set screw. A machined flat should be supplied at the mounting location when stud mounting the sensor. The location and installation of the sensor are critical for successful operation of the SBS Balance System. Because of differing machine characteristics, Vibration Sensor location is specific to the machine model.
  • Page 12 Maintenance Note: SBS Cable connectors are IP67 fluid sealed when closed, but subject to contamination when open. Care must be taken to clean out the pin area of cable connectors prior to each re-connection to prevent premature connector failure.

    The internal balancer shown with cabled connection to the SBS collector, which is mounted separately at the rear end of the spindle (not pictured). With other versions of the balancer, the collector can also be mounted at the wheel end of the spindle, directly attached to the balancer, eliminating the need for the cable bore down the center of the spindle.

    When in Automatic Balance mode press this button to access the Manual Weight Movement screen, which allows the user to change position of the weights in the installed SBS balancer. When operating in Manual Balance mode, this button is used to perform various steps in the manual balance process.

  • Page 16: Main Screen

    Main Screen This is the main display screen of the SB-1000, regardless of the balance mode set (automatic or manual). The basic features are as follows: 1. RPM indication. RPM values will not display if there is no incoming signal (spindle is stopped, or RPM sensor is missing or shorted).

  • Page 17: Preparing To Set Operating Parameters

    Limit The SBS Balance System will automatically balance to a user specified low-limit of vibration, the Auto- Balance Limit. The Limit represents the best balance achievable, and is the target vibration level during an automatic balance cycle. It is factory set at 0.4 microns displacement. A balance Limit of 1.0 micron or less is generally considered adequate for most applications.

  • Page 18: Timing Of Auto-Balance

    Balance mode uses an SBS Balancer to perform fully automatic balancing operations. Manual Balance mode uses an RPM sensor instead of the SBS Balancer. In this mode the control acts as a balance analyzer and directs the user how to manually position balance weights on the spindle assembly to achieve balance. Press and hold the Setup button for one second to display the balance mode selection screen.

    The edit range is (Tolerance + 0.2) to 99.99. Critical RPM setting is displayed at the next press of the Setup button. The Critical RPM indicator flashes to emphasize this mode. The edit range is 300 to 30100, and OFF displays 0. SBS System – SB-1000 Operation...

  • Page 20: Automatic Balance Operation

    Manual Weight Movement - Automatic Balance Mode The SB-1000 in Automatic Balance also allows the weights in the SBS Balancer to be operated manually. The ability to move the balance weights is useful for performing diagnostic tests and allows operators to manually balance machines where needed.

  • Page 29: Hardwire Interface

    Hardwire Interface Interfacing the SB-1000 with a CNC or PLC machine controller is supported via a hardwire interface. The hardwire interface is provided via a standard DB-25 connector located on the rear panel. Because of the many possible variations and configurations of cabling required for such an interface, it is left to the operator to supply the necessary cable.
